Question

I want to use only the chooser dialog (shown below)

from the TimePicker control included in the Silverlight Toolkit for Windows Phone. Normally this dialog only appears when a user clicks on the TimePicker control listbox.

I would like to bypass the listbox altogether and launch the chooser dialog when a button is pressed.

Is this possible or would I have to create a custom control for myself.

Answer 1

Create class that inherited from TimePicker, and use ClickTemplateButton() to simulate click behavior:

public class CustomPicker : TimePicker
{
    public void ClickTemplateButton()
    {
        Button button = (GetTemplateChild("DateTimeButton") as Button);
        ButtonAutomationPeer peer = new ButtonAutomationPeer(button);
        IInvokeProvider provider = (peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider);

        provider.Invoke();
    } 
}

When this class is created, create CustomPicker in xaml. Don’t forget to add xmlns

 xmlns:local="clr-namespace:CustomPickerNamespace"


 <local:CustomPicker x:Name="customPicker" .../>

And then call you can show it from code:

 customPicker.ClickTemplateButton()
